Module development and code questions

If an anonymous user partly fills in a form, then leaves the page for whatever reason, it would be good if the work he/ she already did was preserved, at least for the duration of his current session. Any solutions for this?

Good day. I'm trying to get the id of a node chosen by the user in a field form of type select...at the bottom, I attach my code for review.

My class extends FormBase and use the following namespaces:

I have been submitting an error when sending my Drupal form, the code is designed to insert the values of a select type field in my database. I do not know what I'm failing but I've been trying to find an answer for over a week and I could not.

/*METODO CONSTRUCTOR DEL FORMULARIO -  buildForm*/

Public function buildForm(array $form, FormStateInterface $form_state) {

  $form['WishForm'] = [
    '#type' => 'fieldset',
    '#title' => $this->t('Favorites'),
  ];

Hello,

I am totally new to Drupal 8 module development and after searching in different forum I have still not found an answer to something I consider really basic.

Apologies if my question kind of newbie.

I would like to build some custom modules and make their visibility change at runtime for the currently logged on user.

So let say that user X logs on the Drupal site and clicks a check box on custom module A

I am looking to create a custom rule where a webform will only be displayed every 3 or 6 months if a user accessed the page using the same IP Address.

They would have to accept the T&Cs if the IP Address has not been used before but if it has been logged then the page should not reappear for the user.

Is this possible?

Hello !

The problem is when I go in the WYSIWYG (see image)

I can change colors of the background, width etc.. but when I save/publish the background and the width settings it doesn’t work.. (see image)
